If your water pump is starting to fail, you may notice coolant leaks, or even hear a whining noise coming from under the hood. If you think your water pump is starting to fail, replace it as soon as you can. The main downside to an electric water pump is you may also notice nothing - nothing but overheating! Keep your eyes peeled for warning signs it may be time to replace your water pump. N54 and N55 engines are prone to water pump failure - replace every 60,000 miles. Comes with electric water pump and installation hardware. Aluminum mounting bolts are one time use. Replace every time the water pump is removed.

Overflow hoses connect the radiator and the expansion tank to store overflow of coolant. As pressures in the cooling system increase due to coolant temperatures, a valve on the radiator cap permits coolant back into the reservoir to help ease the build-up of pressure and prevent coolant loss. If your hose is leaking or damaged, we recommend swapping it out with this replacement from Vaico.
